Lunev" Subject: [Qemu-devel] [PATCH 07/10] qga: added empty qmp_quest_get_fsinfo functionality. X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org From: Olga Krishtal We need qmp_quest_get_fsinfo togather with vss-provider, which works with volumes. The call to this function is implemented via FindFirst/NextVolumes. Moreover volumes in Windows OS are filesystem unit, so it will be more effective to work with them rather with devices.
